Designing a successful library school field experience
No full textTo share the library school field experience paradigm that the authors developed after their successful participation as a supervisor and student.
Design/methodology/approach – A review of field experience literature is provided. The field experience paradigms and perspectives pertaining to the supervisor and the student are explained. The paradigm is suggested as a model for field experience participants and their supervisors.
Findings – The field experience paradigm for the supervisors elucidates the stages – planning, training, mentoring and evaluation. The paradigm for students explains the phases – awareness, interests, planning and participation.
Research limitations/implications – The focus of the field experience, from which the paradigm emanated, was to train and prepare the student for agricultural librarianship in an academic library. The application of the paradigm may vary for different situations.
Practical implications – The paradigm is expected to be useful for supervisors and students of field experience programs.
Originality/value – This paradigm stems from the participation of the authors as a field experience supervisor and student. The steps and methods the authors followed will help advance future field experience programs

Vector resonances in weak-boson-fusion at future pp colliders
No full textWe present a first estimate of the reach of future pp colliders, the 14 TeV LHC and a futuristic 100 TeV pp collider, on a vector resonance, specifically a W′, produced via weak-boson-fusion, and decaying dominantly into tb. The analysis is motivated by Composite Higgs, Randall-Sundrum and Little Higgs scenarios, which predict the existence of vector resonances with a large coupling to W and Z longitudinal bosons. In particular, in composite Higgs models with partial compositeness, the standard Drell-Yan production channel is suppressed at large coupling while the weak-boson-fusion is enhanced and could thus provide a unique opportunity to directly test the large coupling regime of the theory. We outline a search strategy for the W′ in the weak-boson-fusion channel and present the reach of future colliders on the W′ mass vs coupling parameter space
Making ereference works findable
No full textThe Internet has significantly changed how libraries provide and library users access information. Libraries increasingly acquire electronic reference (eReference) books while collection of their print counterparts is diminishing. eReference books are not found on libraries' reference shelves and may easily go unnoticed. Libraries face the dilemma of how to make eReference books more accessible to patrons since they are buried in the catalog. K-State Libraries are addressing this challenge by utilizing enhanced metadata behind OPAC records to create browseable eReference lists. The lists are also published as RSS feeds which can be pushed to users. The article describes an approach that does not require programming skills and may be used by subject librarians and catalogers to make eReference books more accessible to patrons
A number theoretic estimate of Davenport from a functional analytic viewpoint
No full textWe consider the problem of the identification of real continuos functions defined on [0,1], by means of the sums of the values f(a/n) with a=1,...,n (this is Fine's problem). This is not possible, in general (Besicovitch example), but we prove that it may be the case under auxiliary condition. We also study the behavior of a well known exceptional function
Extremal values of \Delta(x,N)=\sum\sb {n
No full textThe function Delta(x,N) (which measures the discrepancy of Euler's phi function) as defined in the title is closely associated to several problems in the upper bound sieve.It is also known via a classical theorem of Franel that certain conjectured bounds involving certain averages of Delta(x,N) are equivalent to the Riemann Hypothesis.We improve the unconditional bounds which have been hitherto obtained for Delta(N) and show that these are close to being optimal
Links between \Delta(x,N)=\sum\Sb n\leq xN\\(n,N)=1\endSb 1-x\phi(N) and character sums.
No full textWe express Delta(x,N), as defined in the title, for x=a/q and q prime in terms of values of characters modulo q.
Using this, we show that the universal lower bound for Delta(N)= sup|Delta(x,N)| can, in general, be substantially improved when N is composed of primes lying in a fixed residue class modulo q.
We also prove a corresponding improvement when N is the product of the first s primes for infinitely many natural numbers s
Bloch wall anomaly at the canted-ferromagnetic order-order transition of mixed double-exchange/superexchange magnetic systems
No full textIn mixed coupled, but still magnetically polarized compounds. order-order transitions occur at which occasion the Bloch wall thickness delta can go to zero. This is demonstrated for a deGennes mixed double-exchange/superexchange situation. Experimentally, such Bloch wall anomalies can be detected via Bloch wall enhanced NMR. We discuss one example, i.e. the intermetallic compound MnAs
Factorization of isometries of hyperbolic 4-space and a discreteness condition:
No full textGilman's NSDC condition is a sufficient condition for the discreteness of a two generator subgroup of PSL(2,C). We address the question of the extension of this condition to subgroups of isometries of hyperbolic 4-space. While making this new construction, namely the NSDS condition, we are led to ask whether every orientation preserving isometry of hyperbolic 4-space can be factored into the product of two half-turns. We use some techniques developed by Wilker to first, define a half-turn suitably in dimension 4 and then answer the former question. It turns out that defining a half-turn in this way in any dimension n enables us to generalize some of Gilman's theorems to dimension greater than or equal to 4. We also give an exposition on part of Wilker's work and give new proofs for some of his results.Ph.D.Includes bibliographical references (p. 52-53)by Karan Mohan Pur
Bibliographics for the 983 eprints in the live archives of E-LIS : trends and status report up to 7th July 2004, based on author-self-archiving metadata
No full textThe priority for ideas and philosophy related to "Network Theory" have been traced back and documented by Braun(2004),and credit goes to Karinthy(1929).The IT has empowered to realise it, as the most practical phenomena and it is no more a humour. The OAI (Open Archives Initiatives)and ACIS (Academic Contributor Information System)are progressive in the direction ,which may lead to realise the "Collective Genius" at global level. Focus of present study is on Author-Self-Archiving (A-S-A)Metadata of the 983 Eprints in the Live Archives of the E-LIS (EPrints of Library and Information Science),which were approved till 7th July 2004.The A-S-A Metadata was used for librametric analysis. Self-explanatory bibliographics are illustrated.The highlights include: Conference papers (34%); highest approval, June 2004 (28%); published archives (76%);not refereed (52%); not in public domain (60%); highest self-archiving-author (De Robbio, Antonella).The Nos. of EPrints having single JITA domain specifications were: Theoretical and general aspects of libraries and information(27); Information use and sociology of information(80);Users,literacy and reading(13);Libraries as physical collections(30);Publishing and legal issues(57);Management(13);Industry, profession and education(36);Information sources, supports, channels(113) ; Information treatment for information services, Information functions and techniques (101); Technical services libraries, archives and museums(25); Housing technologies(1); Information technology and library technology(92); and Inter-domainery (395) i.e. having specifications of two or more than two JITA classes
